Here is a list of a few carrier branded tablets to specifically avoid at all costs:

Any Acatel Tablet

The Verizon Ellipsis

Insignia (Best Buy + Verizon Exclusive)

To make matters worse, most carrier branded tablets will actually cost you more in payments then they are actually worth in monthly payments. Even the almost free tablets have high profit margins for carriers due to the cost of the data plan and commitments.

If you must have a LTE Tablet – It is best to go with a Unlocked Tablet such as a Samsung Galaxy Tab LTE, Nexus 9, iPad with LTE or a Microsoft Surface with LTE. Unlocked tablets also have a higher resale value which can help if you plan to upgrade your tablet in the future.
